Received: 9 August 2006; in revised form: 5 September 2006 / Accepted: 5 September 2006 / Published: 6 September 2006 Abstract: A simple, efficient, and general method has been developed for the synthesis of various α-aminophosphonate derivatives 4a-4l by treatment of substituted benzaldehydes and aniline with bis(2-methoxyethyl)- or bis(2-ethoxyethyl) phosphite under microwave irradiation without solvents and catalysts. The products were characterized by elemental analysis, IR, 1H-NMR, 13C- and 31P-NMR spectra. The X-
